Why is the oxidation state of o2- more likely than o6+ explain ?

Because more energy is required to form ion.

Explanation:

Oxygen is the 8th element of the periodic table which belongs to Group 16.

The electronic configuration of the element is:

The number of valence electrons are 6 which is not a stable electronic configuration.

To attain stable electronic configuration, this element will either loose 6 electrons to form ion or gain 2 electrons to form ion.

The loosing of 6 electrons require a huge amount of energy and is an unfavorable reaction. Hence, this element will gain 2 electrons easily and form ion.

This element is considered as a non-metal because it gains electron to attain stable electronic configuration.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
